ABSTRACT:
An integrated circuit device comprising: a circuit which uses encryption; and an encapsulation packaging layer; in which the circuit is responsive to at least one physical parameter of the encapsulation to apply the encryption and/or decryption by reading the key therefrom, so that tampering with the encapsulation to gain access to the circuit causes the encryption and/or decryption to fail.
